Revealing mistake: On the way to the basketball game against 16, when all the guys are pushing Chet's station wagon down the street, it's Kevin Tighe's double who is pushing the car, and he looks nothing like Kevin.
Revealing mistake: When Dixie's in the basement asking Gary why the lab is still backed up, the next shot shows the plumber working in the cabinet under the sink, but when it cuts to the next shot the plumber is gone, his tool box is closed, things are different/missing from the counters, and the tables and stools have been turned over with a mess all around, before the explosion even occurs.
Revealing mistake: When the woman from the car accident is in the ER, she goes into V-fib, so Brackett, Morton, Roy and Johnny work on her and defib four times without success, and as we hear the hum of the flatlining, the camera pans to the left just low enough so that we can see her lying on the gurney, with her blue shirt still buttoned up.
Revealing mistake: At the movie studio, when the actor who plays Dr. Ned is loaded onto the ambulance stretcher, their set's 'fake' window area is the same as Rampart's 'real' hallway later in the episode. We can see this when Brackett, Early and Dix walk down the hallway to kick Dr. Ned's film crew out of his room. Pretty funny to see the same chairs, wall, window with painted exterior backdrop and color stripes on the floor. This area of Rampart can also be seen in the previous episode 'Family Ties', when the clock radio shorts out causing a fire in the patient's room.
Revealing mistake: After Johnny's line gets snarled while testing Wally's equipment at the studio, when Roy lowers himself on his own line wearing his lifebelt, we can see the added carabiners that are attached to the lifebelt which go down into Roy's pants, and are presumably attached to the extra support the actor is wearing under his pants.
Revealing mistake: At the studio, in the overhead shot just as the squad is about to reach the building where Johnny will be testing Wally's equipment, the 'Black Tower', which houses Universal's executive offices, is visible in the background, and then in the roof shots when each of the guys repels down individually, the Sheraton-Universal is visible in the background.
Answer: It is standard practice to wet down driveways so that they stand out in a long shot.
